Currently the MM7000 uses barcodes to identify a location or product which enables the thermometer to record not only the accurate temperature, time and date of the measurement but also the unique identity of whatever has been measured. Up to 1,000 measurements can be recorded, stored and downloaded to a PDA or computer, using the instrument’s Bluetooth capability.
The radical change which has been introduced is a feature which assigns alarm values to a barcode. The MM7000 uses these to give a visual warning of a Low or High alarm for a specific barcode. Once programmed every time the MM7000 scans the barcode an alarm indication will be shown on the display.
The new alarms can be user-set to reflect whichever critical temperature range the customer chooses. Each barcode includes a unique alpha/numeric code which represents the pre-set temperature range including the high and low alarm values. If these alarm values are exceeded the user will be alerted and can take corrective action straight away.
Food Case Studies
A good example of the enhanced functionality is when used with chilled food monitoring. Chilled food must be stored between 0 °C and 5 °C, with 0 °C and 5 °C being the high and low alarm values, so that an alarm would be generated for any temperatures not within this range.
Similarly for certain types of hot food which must achieve a core temperature of for example 60 °C the user would set 60 °C as the low alarm and then choose a suitable higher temperature for the high alarm, ensuring that at least 60 °C has been achieved.
TM Electronics MD, Tom Sensier, says: “Faced with a bewildering number and variety of required temperature checks, there will no longer be any need to remember a series of critical temperatures as these will have been pre-set. Also corrective action can be taken on the spot rather than waiting until after the critical event to find out that something went wrong.”
